程序主要作用是通过串口下载VxWorks到ARM Flash ROM,主要过程是初始化ARM硬件,初始化串口UART1,从串口接收VxWorks image到DRAM,初始化Flash ROM.最后将DRAM中的VxWorks写入Flash ROM. ARM 串口与PC机串口连接,由PC机下载(download)VxWorks 到主板Flash ROM.
该程序对学习和理解ARM编程很有帮助.为了便于理解,这里我全部采用实际地址,不用宏定义.
程序语言为 ARM 汇编,具体过程参考ARM编程,具体寄存器接口定义参见ARM硬件手册
-A major role in the procedure through the serial port to download VxWorks to ARM Flash ROM, the main process is to initialize ARM hardware, initialize serial UART1, receive from the serial port VxWorks image to DRAM, initialization Flash ROM. Finally, in the DRAM VxWorks write Flash ROM. ARM serial machine with PC serial port to connect from PC machine to download (download) VxWorks to the main board Flash ROM. the process of learning and understanding of ARM programming helpful. In order to facilitate understanding, I used the actual address, not the definition of macro. programming language for the ARM compilation, the specific reference ARM programming process, the specific register interface definitions see ARM hardware manual
